CyTime™ Sequence of Events Recorder

Sequence of Events Recorder (SER-32e)

The CyTime Sequence of Events Recorder (SER) provides precise 1 millisecond time-stamped event reporting for 32 channels to enable root-cause analysis and advanced system diagnostics. It also provides time synchronization to downstream devices with support for several time protocols such as Precision Time Protocol (PTP) and IRIG-B.


  • Color Touchscreen: The SER-32e has a large 4.3” color touchscreen for easier menu navigation, device setup, diagnostics and input status.
  • Time Synchronization: Supports Precision Time Protocol (PTP), IRIG-B, DCF77, Network Time Protocol (NTP), Modbus TCP/IP, 1 per 10 and ASCII RS-485.
  • Embedded Web Server: Connect over Ethernet via a standard secure web browser (HTTPS), with no proprietary software needed.
  • Fully encrypted (256-bit) communications for configuration and data exchange.
  • Easy Integration: With support for Modbus TCP and/or RESTful API, data is easily integrated into any SCADA, Power Monitoring and Building Management System.
  • Extended Control Power Ride-through: An extended control power ride-through to ensure critical events are captured during power loss/outage.
  • Expansion Slots: The SER-32e also includes 2 I/O expansion slots to support expansion modules adding up to 16 additional inputs or outputs.
